以下、本発明の車両外装装飾品をラジエータグリルに具体化した一実施形態について図面を参照しながら説明する。なお、以下の説明においてラジエータグリルの「上」「下」「左」「右」は、図２に示す矢印Ｙ１の方向を上下方向とし、矢印Ｙ２の方向を左右方向とする。また、ラジエータグリル１１の「前」を車両の前進方向側とし、「後」を車両の後進方向側とする。   Hereinafter, an embodiment in which a vehicle exterior decorative article of the present invention is embodied in a radiator grill will be described with reference to the drawings. In the following description, for the “upper”, “lower”, “left”, and “right” of the radiator grille, the direction of the arrow Y1 shown in FIG. Further, “front” of the radiator grille 11 is defined as the forward direction side of the vehicle, and “rear” is defined as the backward direction side of the vehicle.

図１及び図２に示すように、ラジエータグリル１１は、車両１０の前部に設けられるとともに、ラジエータ（図示せず）の前方に設けられる部品であり、フロントグリルとも呼ばれる。詳しくは、ラジエータグリル１１は、車両１０のフロントバンパー１７とフードパネル１８との間で、かつ、一対のヘッドライト１９との間に位置するように車両１０に取り付けられている。   As shown in FIGS. 1 and 2, the radiator grille 11 is a component that is provided in the front portion of the vehicle 10 and in front of a radiator (not shown), and is also called a front grille. Specifically, the radiator grill 11 is attached to the vehicle 10 so as to be positioned between the front bumper 17 and the hood panel 18 of the vehicle 10 and between the pair of headlights 19.

図２に示すように、前記ラジエータグリル１１は、車両１０の車幅方向（図２では左右方向）へ横長に延びる四角枠状をなす外枠１２と、該外枠１２の短辺方向（図２では上下方向）に対向する上下両部を連結する複数の縦バー１３とが一体形成されてなる。ラジエータグリル１１において、前記車幅方向の中央部に位置する縦バー１３ａには、楕円板状をなすオーナメント１４を装着するための凹部１５が形成されている。   As shown in FIG. 2, the radiator grille 11 includes an outer frame 12 having a rectangular frame shape extending horizontally in the vehicle width direction of the vehicle 10 (left and right direction in FIG. 2), and a short side direction of the outer frame 12 (see FIG. 2). In FIG. 2, a plurality of vertical bars 13 that connect both the upper and lower portions facing each other in the vertical direction) are integrally formed. In the radiator grill 11, a recess 15 for mounting an ornament 14 having an elliptical plate shape is formed in the vertical bar 13a located at the center in the vehicle width direction.

また、前記外枠１２における車幅方向の両側部及び各縦バー１３の間には、複数のスリット１６が形成されている。外枠１２の両側部、縦バー１３、及びスリット１６は、それぞれ車両１０のフロントバンパー１７からフードパネル１８に向かって斜めに流れるように形成されており、スポーティな切れの良さと味わい深い上質さとを表現している。   A plurality of slits 16 are formed between both side portions of the outer frame 12 in the vehicle width direction and between the vertical bars 13. Both sides of the outer frame 12, the vertical bar 13, and the slit 16 are formed so as to flow obliquely from the front bumper 17 of the vehicle 10 toward the hood panel 18, and express a sporty cut quality and a tasteful quality. is doing.

そして、ラジエータグリル１１を中心とする車両１０の前部（前面）は、該車両１０のアイデンティティーを最も強く表す部位であって、人間に例えれば顔面に相当する。このため、車両１０の前部は、車両１０を表現するうえで極めて重要な意匠を担っており、ラジエータグリル１１の前面も車両１０の意匠を担っている。すなわち、ラジエータグリル１１の前面である外枠１２の前面、縦バー１３の前面はラジエータグリル１１の意匠面となっている。   And the front part (front surface) of the vehicle 10 centering on the radiator grille 11 is a part that most strongly represents the identity of the vehicle 10, and corresponds to a face in the case of a human being. For this reason, the front part of the vehicle 10 bears an extremely important design for expressing the vehicle 10, and the front surface of the radiator grill 11 also bears the design of the vehicle 10. That is, the front surface of the outer frame 12 that is the front surface of the radiator grille 11 and the front surface of the vertical bar 13 are design surfaces of the radiator grille 11.

上記ラジエータグリル１１は、ポリカーボネイト樹脂製の基材２１によって透明に形成され、該基材２１によって上記外枠１２及び縦バー１３が形成されている。前記ポリカーボネイト樹脂は、可視光の透過を許容する透明樹脂であり、耐光性及び耐候性に優れるとともに、高い屈折率を有する材料である。そして、基材２１は、前記ポリカーボネイト樹脂の射出成形によって中実状に成形することにより形成され、基材２１は、中実状のポリカーボネイト樹脂によってガラス様に視認されるようになっている。   The radiator grill 11 is formed transparent by a polycarbonate resin base material 21, and the base frame 21 forms the outer frame 12 and the vertical bar 13. The polycarbonate resin is a transparent resin that allows visible light to pass therethrough, and is a material having excellent light resistance and weather resistance and a high refractive index. The base material 21 is formed by solid molding by injection molding of the polycarbonate resin, and the base material 21 is visually recognized by the solid polycarbonate resin.

図２及び図３に示すように、前記基材２１において、前記縦バー１３ａにおける前記凹部１５の下側には、車両１０（ラジエータグリル１１）の前方から見て円形状をなす厚肉部２２が縦バー１３ａに一体形成されている。この厚肉部２２は、縦バー１３及び外枠１２よりも厚肉に形成されている。また、厚肉部２２における車外側の面である前面２２ａは、縦バー１３ａの前面及び外枠１２の下側部に連設されているとともに、縦バー１３ａの前面よりも車外側、すなわち、車両１０の前方へ円弧状に膨出するように形成されている。そして、厚肉部２２は、その前面２２ａが縦バー１３ａの前面と一体様をなし、縦バー１３ａとの一体感を醸し出し、ラジエータグリル１１の意匠面の一部を構成している。すなわち、厚肉部２２の前面２２ａは、ラジエータグリル１１の意匠面に沿って形成されている。   As shown in FIGS. 2 and 3, in the base material 21, the thick portion 22 having a circular shape when viewed from the front of the vehicle 10 (radiator grill 11) is provided below the concave portion 15 in the vertical bar 13 a. Is integrally formed with the vertical bar 13a. The thick portion 22 is formed thicker than the vertical bar 13 and the outer frame 12. Further, the front surface 22a which is the vehicle outer surface in the thick portion 22 is continuous with the front surface of the vertical bar 13a and the lower side portion of the outer frame 12, and is further on the vehicle outer side than the front surface of the vertical bar 13a. It is formed so as to bulge in an arc shape toward the front of the vehicle 10. The thick wall portion 22 has a front surface 22 a that is integrated with the front surface of the vertical bar 13 a, creating a sense of unity with the vertical bar 13 a, and constitutes a part of the design surface of the radiator grill 11. That is, the front surface 22 a of the thick portion 22 is formed along the design surface of the radiator grill 11.

図３に示すように、厚肉部２２は、その前面２２ａの中央部が前方へ最も突出している。そして、厚肉部２２は、前面２２ａの中央から周縁へ向かうに従い円弧状に湾曲するように形成されている。また、前記厚肉部２２は、車内側たる後面２２ｂの中央部が前方へ円弧状に凹むように形成されている。そして、厚肉部２２は、後面２２ｂの中央から周縁へ向かうに従い円弧状に湾曲するように形成されている。また、厚肉部２２は、厚肉部２２の中でも中央部の厚みが最も厚く、周縁部へ向かうに従い厚みが薄くなるように形成されている。   As shown in FIG. 3, the thick part 22 has the center part of the front surface 22a most protruding forward. And the thick part 22 is formed so that it may curve in circular arc shape as it goes to the periphery from the center of the front surface 22a. The thick portion 22 is formed such that the central portion of the rear surface 22b, which is the inside of the vehicle, is recessed forward in an arc shape. And the thick part 22 is formed so that it may curve in circular arc shape as it goes to the periphery from the center of the rear surface 22b. Moreover, the thick part 22 is formed so that the thickness of the center part is the thickest among the thick parts 22, and the thickness becomes thinner toward the peripheral part.

すなわち、厚肉部２２は、中央が周縁よりも厚みの厚い凸レンズ状（本実施形態では凸メニスカスレンズ状）に形成されている。なお、前記凸レンズは、平行光線を収束する作用があり、その収束点で実像を形成するものである。また、厚肉部２２は、広角レンズとしても機能する。その結果、厚肉部２２よりも前方となる視界は、厚肉部２２よりも車内側で実像化されるようになっている。   That is, the thick portion 22 is formed in a convex lens shape (in the present embodiment, a convex meniscus lens shape) whose center is thicker than the peripheral edge. The convex lens has an effect of converging parallel rays, and forms a real image at the convergence point. The thick portion 22 also functions as a wide angle lens. As a result, the field of view ahead of the thick portion 22 is made a real image on the vehicle inner side than the thick portion 22.

そして、図１に示すように、車両１０の前部にラジエータグリル１１が配設された状態では、厚肉部２２は、前記オーナメント１４の下側に位置するとともに、外枠１２の下側部より上側に位置している。車両１０の前部には、その上側から下側へ向かうに従い、外枠１２の上側部、オーナメント１４、厚肉部２２、そして、外枠１２の下側部といった車両１０の前方へ膨出する箇所が連続して配置されている。また、車両１０の前部の一部は、ラジエータグリル１１によってガラス様に視認可能となっている。   As shown in FIG. 1, in the state where the radiator grille 11 is disposed at the front part of the vehicle 10, the thick part 22 is positioned below the ornament 14 and the lower part of the outer frame 12. It is located on the upper side. The front part of the vehicle 10 bulges forward of the vehicle 10 such as the upper part of the outer frame 12, the ornament 14, the thick part 22, and the lower part of the outer frame 12 as it goes from the upper side to the lower side. The places are arranged continuously. Further, a part of the front portion of the vehicle 10 is visible like a glass by the radiator grill 11.

図３に示すように、車両１０において、ラジエータグリル１１における厚肉部２２の裏側（車内側）には、車載カメラ３０が搭載されている。そして、厚肉部２２は、前記車載カメラ３０のレンズとして機能するように、車載カメラ３０の車外側（前側）に配設されている。また、厚肉部２２は、車載カメラ３０から車外側へ膨出するように形成されている。   As shown in FIG. 3, in the vehicle 10, an in-vehicle camera 30 is mounted on the back side (inside the vehicle) of the thick portion 22 in the radiator grill 11. And the thick part 22 is arrange | positioned in the vehicle outer side (front side) of the vehicle-mounted camera 30 so that it may function as a lens of the said vehicle-mounted camera 30. FIG. Further, the thick portion 22 is formed so as to bulge from the in-vehicle camera 30 to the outside of the vehicle.

そして、前記車載カメラ３０を搭載した車両１０において、ラジエータグリル１１を形成する基材２１は、透明のポリカーボネイト樹脂製であり、ガラス様に視認されるため、厚肉部２２はレンズ（本実施形態では広角レンズ）としての機能を発揮する。すなわち、厚肉部２２よりも前方であり、厚肉部２２の全周側（上下左右）の視界は、厚肉部２２により実像化される。そして、厚肉部２２によって実像化された車両１０前方（車外）の視界は、車載カメラ３０によって撮像され、車室内のモニタ（例えば、ナビゲーションシステムの画面）に一画面表示される。   In the vehicle 10 equipped with the in-vehicle camera 30, the base material 21 forming the radiator grille 11 is made of transparent polycarbonate resin and is visually recognized like a glass. It will function as a wide-angle lens. That is, the field of view on the entire circumference side (upper and lower left and right) of the thick part 22 is realized by the thick part 22 in front of the thick part 22. The field of view in front of the vehicle 10 (outside the vehicle) realized by the thick portion 22 is captured by the in-vehicle camera 30 and displayed on a single screen on a monitor (for example, a screen of a navigation system) in the vehicle interior.

前記の実施形態によって発揮される効果について、以下に記載する。
・ ラジエータグリル１１は、透明樹脂であるポリカーボネイト樹脂製の基材２１によって形成され、該基材２１には車載カメラ３０のレンズ（広角レンズ）として機能する厚肉部２２が一体成形されている。そして、厚肉部２２により車両１０前方（車外）の視界を広角で実像化することができ、該視界を車載カメラ３０により良好に撮像することができる。また、例えば、車両１０前方の視界を撮像するために、車載カメラ３０を車両１０前方へ突出させる必要がないため、該突出のための構成を設けることなく簡易な構成で車両１０前方の視界を良好に撮像することができる。 The effects exhibited by the above embodiment will be described below.
The radiator grill 11 is formed of a polycarbonate resin base material 21 that is a transparent resin, and a thick portion 22 that functions as a lens (wide angle lens) of the in-vehicle camera 30 is integrally formed on the base material 21. The field of view in front of the vehicle 10 (outside the vehicle) can be made into a real image at the wide angle by the thick portion 22, and the field of view can be favorably captured by the in-vehicle camera 30. Further, for example, since it is not necessary to project the in-vehicle camera 30 forward of the vehicle 10 in order to image the field of view ahead of the vehicle 10, the field of view ahead of the vehicle 10 can be obtained with a simple configuration without providing a configuration for the projection. Good imaging can be performed.

・ また、厚肉部２２は、基材２１に一体成形されている。このため、例えば、レンズ機能を有する部材を基材２１に別体で取り付けて車載カメラ３０のレンズとする場合のように、レンズとラジエータグリル１１とが別色となったり、ラジエータグリル１１に対する別体感が生じたりすることが無く、ラジエータグリル１１の意匠面（前面）に一体感を出すことができる。特に、厚肉部２２は、その前面２２ａが縦バー１３ａ及び外枠１２、すなわち、ラジエータグリル１１の意匠面に沿うように一体成形されているため、ラジエータグリル１１は著しく高い意匠性を有するものとなる。加えて、背景技術では、カメラの使用時には、エンブレム（本実施形態ではオーナメント１４に相当）を回動させ、さらに、カメラを車両前方へ突出させる構成であったが、本実施形態では、車載カメラ３０の使用時であっても厚肉部２２をはじめラジエータグリル１１の意匠面は変化しない。このため、カメラが突出することによるラジエータグリル１１、ひいては車両１０前面の意匠性が悪化することを無くすことができる。   In addition, the thick portion 22 is integrally formed with the base material 21. For this reason, for example, the lens and the radiator grille 11 have different colors as in the case where a member having a lens function is separately attached to the base member 21 to form the lens of the in-vehicle camera 30, or the lens and the radiator grille 11 are separated from each other. A feeling of unity does not occur and a sense of unity can be given to the design surface (front surface) of the radiator grille 11. In particular, the thick wall portion 22 is integrally formed so that the front surface 22a thereof is along the vertical bar 13a and the outer frame 12, that is, the design surface of the radiator grille 11, so that the radiator grille 11 has a remarkably high design property. It becomes. In addition, in the background art, when the camera is used, the emblem (corresponding to the ornament 14 in the present embodiment) is rotated, and the camera is further protruded forward of the vehicle. Even when 30 is used, the design surface of the radiator grill 11 including the thick portion 22 does not change. For this reason, it is possible to eliminate the deterioration of the design characteristics of the radiator grille 11 and the front surface of the vehicle 10 due to the projection of the camera.

・ ラジエータグリル１１は、車両１０の前部といった車両１０を表現する部位に配設される。そして、厚肉部２２をはじめラジエータグリル１１は透明であり、ガラス様に視認可能である。このため、一般のラジエータグリルのように塗装が施され有色様をなす場合に比して、ラジエータグリル１１を高い意匠性を有するものとすることができ、ひいては車両１０のイメージを特徴的なものとすることができる。   The radiator grill 11 is disposed at a part representing the vehicle 10 such as the front portion of the vehicle 10. And the radiator grille 11 including the thick part 22 is transparent, and can be visually recognized like glass. For this reason, the radiator grille 11 can have a high design as compared with the case where it is painted and colored like a general radiator grille, and thus the image of the vehicle 10 is characteristic. It can be.

・ ラジエータグリル１１は、ポリカーボネイト樹脂（透明樹脂）を中実状に射出成形した基材２１よりなり、基材２１の形状は、射出成形用の金型によって所望する形状とすることができる。本実施形態では、厚肉部２２が、車両１０の前部に車載カメラ３０を搭載するのに好適な位置（車幅方向の中央部）に配設されるように基材２１が成形されている。したがって、ポリカーボネイト樹脂の射出成形によってラジエータグリル１１を形成することで、ラジエータグリル１１全体の設計の自由度を大幅に向上させることを容易にする。   The radiator grill 11 is composed of a base material 21 in which a polycarbonate resin (transparent resin) is solidly injection-molded, and the shape of the base material 21 can be set to a desired shape by a mold for injection molding. In the present embodiment, the base material 21 is molded so that the thick wall portion 22 is disposed at a position suitable for mounting the in-vehicle camera 30 on the front portion of the vehicle 10 (the center portion in the vehicle width direction). Yes. Therefore, by forming the radiator grille 11 by injection molding of polycarbonate resin, it is easy to greatly improve the design freedom of the entire radiator grille 11.

・ 厚肉部２２は、ラジエータグリル１１における車幅方向の中央部に形成されている。このため、例えば、厚肉部２２が車幅方向における一端側に偏って形成されている場合のように、車載カメラ３０によって撮像される視界が、車幅方向の一端側に偏ることが防止される。その結果として、車載カメラ３０により車幅方向両側の視界を均等に撮像することができる。   The thick portion 22 is formed in the center portion of the radiator grill 11 in the vehicle width direction. For this reason, for example, the field of view captured by the in-vehicle camera 30 is prevented from being biased toward one end side in the vehicle width direction, as in the case where the thick wall portion 22 is formed biased toward one end side in the vehicle width direction. The As a result, the in-vehicle camera 30 can uniformly image the fields of view on both sides in the vehicle width direction.

・ 厚肉部２２は、車載カメラ３０よりも車外側、すなわち、車両１０前方へ膨出する凸レンズ状に形成されている。このため、ラジエータグリル１１の意匠面は、外枠１２の上側部、オーナメント１４、厚肉部２２の前面２２ａ、及び外枠１２の下側部といった車両１０の前方へ連続して膨出する部位によって形成されている。したがって、連続する膨出部位によってラジエータグリル１１に統一感を出してラジエータグリル１１を高い意匠性を有するものとすることができる。   The thick portion 22 is formed in a convex lens shape that bulges out of the vehicle-mounted camera 30, that is, in front of the vehicle 10. Therefore, the design surface of the radiator grille 11 is a portion that continuously bulges forward of the vehicle 10 such as the upper portion of the outer frame 12, the ornament 14, the front surface 22 a of the thick portion 22, and the lower portion of the outer frame 12. Is formed by. Therefore, the radiator grille 11 can have a sense of unity by the continuous bulging portion, and the radiator grille 11 can have high designability.

・ 厚肉部２２は、車載カメラ３０よりも車外側、すなわち、車両１０前方へ膨出する凸レンズ状に形成されており、厚肉部２２が実像化して車載カメラ３０で撮像される画像は厚肉部２２の全周囲の視界となっている。このため、車室内のモニタには車両１０前方の視界が一画面で表示される。したがって、例えば、車載カメラ３０のレンズとしてプリズムを用い、車室内のモニタに車両１０前方の視界が左右の二画面に分割表示される場合に比してモニタでの視認性を良好なものとすることができる。   The thick portion 22 is formed in the shape of a convex lens that bulges out of the vehicle-mounted camera 30, that is, in front of the vehicle 10, and the image captured by the vehicle-mounted camera 30 when the thick wall portion 22 becomes a real image is thick. The entire perimeter of the meat part 22 is visible. For this reason, the field of view in front of the vehicle 10 is displayed on a single screen on the monitor in the passenger compartment. Therefore, for example, a prism is used as the lens of the in-vehicle camera 30, and the visibility on the monitor is improved compared to the case where the field of view in front of the vehicle 10 is divided and displayed on the left and right screens on the monitor in the vehicle interior. be able to.
